JOHN NYLANDR, 0F MUSKEGON, MICHIGAN.

-HosE-coUrLING.

To all whom it may concern:

Be it known that I, JOHN NYLANDER, residing at Muskegon, in the countyof Muskegon and State of Michigan, have invented a new and ImprovedHose-Coupling, of which the following is a specification.

This invention relates to that class of coupling devices in which theopposing members have interlocking portions, adapted, under oneadjustment, to snap into a locked engagement and under anotheradjustment to be disengaged and readily separated.

Myinvention has for its object to provide a hose coupling of the generalcharacter stated of a simple and economical construction, in which thecoperating parts are especially so designed that the operation ofcoupling is easily effected without the use of screws and the like, inwhich the parts are held Water-tight and so arranged that the packingcan be easily replaced when Worn.

My invention consists in the improved construction and novel arrangementof the parts hereinafter fully described, specifically pointed out inthe appended claims and illustratedin the accompanying drawing, inwhich:

Figure 1, is a perspective view of my improved hose coupling, partsbeing separated to the better illustrate their construction. Fig. 2, isa longitudinal section thereof taken on the line Qr-Q of Fig. 3, theparts being in their locked position. Fig. 3, is a transverse section ofthe same on the line 3-3 on Fig. 2. Fig. 4, is a longitudinal section ofthe coupling device taken on the line 4--4 on Fig. 5, the spring detentbeing shown pulled back to release the lug carrying nipple. Fig. 5, is across section of the same on line 5 5 on Fig. 4. Fig. 6, is a crosssection ta'ken on the line 6- 6 on Fig. 2. Fig. 7, is a similar viewon'the line 7-7 on Fig. 4. Fig. 8, is a side View of the completecoupling.

In carrying out my invention, I provide a coupling member consisting 'ofa tubular body 1 provided near one'end with an annular internal flange10 that forms a Yseat for the packing rings 2-2*, one for each sidethereof and that end of the said body near the flange 10, is internallythreaded to receive the threaded end 8 of one of the hose nip les 30that is held water-tight on the b'odml by screwin ,it ti htly againstthe .pac g lring 2. f he en of the coupling Specication ofIietterslatent.

member 1, opposite the threaded end, has a pair of oppositely disposedbayonet recesses 4-4, the transverse portions L1.0--40 of which inclinetoward the packing ring 2a whereby to draw the nipple 50 of the hosesection 5 tightly against the said ring 2a when the said nipple 50 iscoupled to the member 1.

61-#61 and have their free ends 62 slightlyl turned out for positivelyengaging with lifter cams presently again referred to. To

facilitate the snap action of the lugs theyy vhave one edge 63 beveled.So far as de` scribed it will be readily apparent that by inserting thenipple 50 into the coupling member 1 with the lugs 6 pushed into thebayonet recesses 4t and giving the nipple a slight rotary movement, thepins 51 will slip over the lug 6 and the latter when the pins 5l passthem, snap back and hold the nipple from being turned off the member.

To provide for readily uncoupling 'the hose sections, I use a sleevethat is loosely mounted upon the member 1 and the said sleeve comprisesa central ring 9, end cap rings -71 and a removable face ring 72. Whenthe parts are 'assembled -for use the several rings 7, 70, '71 and 72are riveted or otherwise held together to cause them toyplays a leafspring 9, one end of which is fastened to the tubular body 1. Spring 9is bow-shaped` to t closely around the member 1 and its -free endengages the stop shoulder 78, the purpose of the spring bei to returnthe ring members to their norma position, after :they have been manuallyturned to unlockthe snap lugs from the locking pins 51.

the parts then being as shown in Figs. 2, 3 and 6. To uncouple the partsthe unlocking ring is positively rotated in the membery 1, in thedirection indicated bythe arrows on Figs. 3 and 6, which Causes the cams76 to lift thewlugs 6 back to the position shown in Fig. 5 and-frees thenipple 50 whichcan then be freely turned and pulled out of the member 1.In turning the ring as stated,

the spring is turned up, as shownin Fig. 7, and put under sufficienttension to return the ring and the lifter cams tothe normal po'- sition,,Shown in Fig. 3. l

What I claim is:

into the tubular member, a bayonet joint for holding the said nipple andthe tubular member together; of a spring latch for holding the bayonetjoint locked, said latch being mounted on the tubular member, and

a. ring encircling the tubular member, and,I .rotatable thereon and awedge device car.

ried by said ring for engagin and releas-l ing the spring latch vfromthe ayonet joint when turned in one direction.l

2. In a hose cou ling, ,the combination with atubular mem er, a nippleinsertible into the tubular member, arbayonet joint for holding thesaid-nipple and the tubular member together; of a sprin latch forholding the bayonet joint locke said latch being mounted on the'tubularmember, and a ring encircling the tubular member, and

' rotatable thereon, a wedge device carried by, and in said ring forreleasing the sprin latch from the bayonet joint when turiie `in onedirection, and a spring device for returning the said ring to its normalposition.

, 3. In a hose coupling, two coupling members, having a` bayonet jointconnection between the same, a leaf spring mounted on one of saidsections, and' havin a lug to en age the bayonet lug of the ot ersection to ock said bayonet joint, a ring rotatably mountedy on saidspring carrying section and havin a chamber to inclose said spring, saidring av-ing a wedge portion to engage the free end of said spring whenlsaid rin is turned in one direction, v to move sai spring to releasesaid bayonet 'oint, -substantially as shown and described.

' 4. In a hose coupling, two coupling memtions, a'spiing male section inone of said chamber por- 1. In a hose cou ling, the combinationwitha'tu'bular mem er, a nipple insertible to lock said bayonet joint, aring rotatably mounted on said spring carrying section and having achamber to inclose saidy spring,

the free end of said spring when said ring is turned in one direction,to -niove said spring to release said bayonet joint, means for limitingthe turning movement of said ring iii one direction, 'and a second leafspring vmounted on first mentioned coupling section andl engaging saidring to move said ring in adirection to normally hold said wedge Vout ofcontact with said first mentioned spring.

5. In a hose coupling, a male and a female section; said male sectionhaving a lug,
